Planns / Questions:

We are ready for at least 20 m Roebel cable manufacturing

- waiting for Bruker material

Questions:

• Should we deliver cable for FRESCA test from Bruker material?

• Does other coated conductor Roebel cables are foreseen for

FRESCA test?

• 9 x 200 mm for resin impregnation test (one piece-1.8 m, current lead?)

• 2*800 layer jump impregnation (one piece-1.6 m)

• 1*1000 mm normal zone propagation (who?, where?)

• 1*6000 mm dummy (TL 226, 15 strands)-Feather-M0 ok!
